I'm Purchasing New Electrode-Less Magnetic Induction Lights

[sherriberry]

That was a waste...reading on how great you thought these lights only to find out you bought a 250w HPS...WTF!

That deal is on eBay all day every day to bro from HTG supply or something like that.

2 pages of reading... ha

yeah, i got 600 watt hps's a few of them and digital ballasts.

if i didnt already have grow lights for veg, i would have bought these lights, but i have 3 t5 8 bay 4ft lights already

i didnt want to invest the money quite yet to take a chance on these new lights.

maybe in the future tho i will buy a couple

While the EFDL seems great ....



- from their web page:

Enviro Tech: "energy efficient 80-90Lm/w and 120-150PLm/W"

http://www.enviro-techlighting.com/par_max_efdl.html

I assume Lm/w is lumens/watt but PLm/W = ? Par Lumens per watt? There is no spectrum on their page, we don't know how much green we have or how much falls on the 4 peak frequencies. But ....

Hortilux 600 watt super HPS = 88,000 lumes = 146 lumens per watt, at the top of the EFDL output and ...

Solarmax 600 watt HPS = 95,000 lumens = 158 lumens per watt, outperforming the EFDL.

.

Is this like TV lighting or Plasma lighting? The canopy penatration on these is as bad or worse than cfl. Does anyone know the canopy penetration of EFDL lights? EFDL = induction light?

How much of their par watts fall in the range we need?

The photo spectrum:

Chlorophyll a, the most important light-absorbing pigment in plants, does not absorb light in the green part of the spectrum.

So as you can see:
Make up of an ideal led panel:
2% UVB Leds for resin and tric production. 380mn
6% Royal Blue Leds 455mn
12% Blue Leds 470mn
30% Red Leds 627mn
50% Far Red leds 660mn

Sunlight contains 4% ultraviolet radiation, 52% infrared radiation and 44% visible light.
I would stay away from amber leds I have seen I studies that show an increase in hermaphrodites.
I will go into Chlorophyll b when I can find the graphic again.

I dont believe Far-Red starts at 660. I believe its right around 700.

heres one of the curves for induction light

and a different model

Early technology yet - watch this space. And watch for prices to come down.

Two successive spam posts, is that really necessary?

there is a you tube video; Indagro on induction grow lights that is very informative. FYI the 500 watt induction lamp produces only 5% more lumens then the 400 watt There is only one company who went to market with a 500 watt induction fixture because the physics of the indcution lamp tap efficiancies as measured in efficacy at 400 watts. This has to do with the fact that the driver runs at a 2.65 KHZ frequency and the electrmagnetic field that excictes the argon gas in the lamp reaches it's full potential, there is no more,with the 400 watt driver. The absolute best induction lamp, which operates on the same principals as a fuorescent lamp except there are no internal electrodes to depreciate is with a 12 blend phosphor. This enable the PAR levels to achieve max chloriphyl absorption at both the 300 and 700 nanometer ranges, giving us the benefit of one lamp for both the vegative and budding phases of our grow. there are charts from the tabs at the bottom of the indagro home page that compare various HID lamps to induction. if you compare the lumen outputs you will see for yourself induction with it's high scotopic values as measured in VEL surpass the HID, LED and T5 for our hobby. peace

i think all of us have seen tons of claims, backed up by some cheap products due to the LED craze over the past few years. That being said, very few procucts actually deliver results. Would like to see some trials or example grows with these units to see what they can do up against HPS.

 

[squarepush3r]

ck out the indagro website and look at the user submitted photos for some start to finish grow pics. these are nothing like an LED in that the claims are backed by science and results. everyone i know is switching over to them because the plants love them and you can actually touch the lamp when it's running for 60% less wattage. Also it's a 100,000 hr rated lamp. Why would anyone not be interested in these features instead of throwing their money at the 'tried and true'.

interesting, the company should give away some lights to rep'd users and have them do detailed grow reports.

 

[squarepush3r]

they do offer a 30 day return. I kept mine because in 24 hours you could tell the difference. The plants had been kind of drooping and they stood straigh up. pretty amazing. ck out the pics on their site.

let me guess, your hair grew back and you won the lottery as soon as you bought this light?

 

[squarepush3r]

Unfortunately no. The LED's were supposed to do that. the induction just grows bud. good guess though

still like to see a grow journal =p

 

[squarepush3r]

cool, keep us up to date with your progress!

I have not had spider mites since I went with the inda-gro 400 series. with the temp from the HPS it was constant battle with those little fuckers

 

[YouGrowBoy]

Chazbolin, I see ALL your posts are related to the induction light. Do you have pics of your garden with induction lights? Do you work for a distributor?

 

[chazbolin]

Lighting is about 80% of my business as I'm an electrical contractor in CA. I was first introduced to induction and LED as retrofit for HID in parking lot applications. So I've had some experience with several different manufacturers and the distributors who rep them. Suffice it to say the LED's fell out of our general area lighting favor when we had 60% mortality within 5 months of a fairly large project and we could not get warranty coverage from the mfg or the distributor. They offered us Cost + 10% on an induction replacement which is what we eventually went with. No more LED retrofits for us.

I have also been growing for about 20 years and was hopeful that the LED's would be an low energy option but here to then LED was less then adequate. I want to share the induction because it is not widely known amongst our community. 200 & 400 series grow pics all under induction. When done right they are a game changer.

 

[YouGrowBoy]

Nice pics and grow. What would you say your watt per sq ft is and what are the color temps of your lights?

In the past I've used HPS, never went to LED's as they never looked like they would work. Been following the sulfur plasma too. I like the florescent quality of induction. Right now I have no garden, but after prop 19 passes things may change. Still haven't pulled the trigger on anything other then HPS but induction looks promising.

 

[chazbolin]

ye induction is certainly promising. What's more important then watts per square foot is the lumen output for induction grow lamps. The VEL per sq/ft is like 166.5 compared to HID which runs around the 97 lm p/watt. so this is considerably more energy from the lamp per watt with peaks in both UV and IR ranges so the plants take in maximum chlorophyll absorption or PAR. but to compare the 1000 watt HPS to the 400 watt induction is like apples and oranges since the 400 does UV and IR and produces more VEL. The current setup replaces 4 of the 1000 watt HPS with 3 of the 400 inda-gro series with yields of around 300 grams per meter and I use the same fixture for veg thru bud without all the heat. good luck and post those pics for us.

 

[YouGrowBoy]

While your garden looks nice, I still want to see a (or do one of my own) live grow with these lights before shelling out $700+ per 400 watt fixture. I need to see live proof, I'm a skeptic.
